Applications The Fluorescein Arsenical Hairpin Binder (FlAsH) method is presented for fluorescence labeling of proteins in living cells. Labeling proteins with the membrane-permeant fluorogenic biarsenical dye fluorescein arsenical hairpin binder-ethanedithiol (FlAsH-EDT2). The membrane-permeant fluorogenic biarsenicals FlAsH-EDT2 and ReAsH-EDT2 can be prepared in good yields by a straightforward two-step procedure from the inexpensive precursor dyes fluorescein and resorufin.

Applications A thiol reactive fluorescent probe for the labelling of proteins. Rhodamine dyes are used extensively in various aspects of fluorescence microscopy because of their brightness and resistance to photobleaching. They are valuable in studies directed at probing changes in orientation and mobility of proteins using fluorescence anisotropy measurements. It is a mixture of the 6-Iodo and 6-chloro.
